[0020] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0022] Next, the clamping device provided by the embodiments of the present application will be described in detail in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0023] Please refer to Figures 1-5, the clamping device disclosed in the embodiments of the present application includes a base 101 and a boss 102. Among them, the base 101 serves as the basic component of the clamping device, and the boss 102 is provided on the base 101 and protrudes from the surface of the base 101. The base 101 and the boss 102 can be of a split structure or an integral structure. When the clamping device clamps the workpiece to be clamped 500, the base 101 contacts the workpiece to be clamped 500, and the boss 102 extends into the interior of the workpiece to be clamped 500, so as to blow air into the interior of the workpiece to be clamped 500 through the air blowing holes provided on the boss 102.

[0024] Among them, the workpiece to be clamped 500 can be an electronic cigarette or other components that need to be purged inside after processing. The embodiments of the present application do not limit the type of the workpiece to be clamped 500.

[0025] The boss 102 is used to extend into the interior of the workpiece to be clamped 500, so that the base 101 and the boss 102 are respectively in contact with the workpiece to be clamped 500. Optionally, the base 101 can be in contact with the end face of the workpiece to be clamped 500, and the boss 102 can be in contact with the inner wall surface of the workpiece to be clamped 500. In this way, it is beneficial to increase the contact area between the clamping device and the workpiece to be clamped 500 and improve the clamping stability of the workpiece to be clamped 500.

[0026] Reference Figure 3 As shown, the base 101 is provided with a first air blowing hole a for connecting the air blowing pipe, and the boss 102 is provided with a second air blowing hole b. The first air blowing hole a is communicated with the second air blowing hole b, and the air blowing pipe can blow air into the interior of the workpiece to be clamped 500 through the first air blowing hole a and the second air blowing hole b. Specifically, the first air blowing hole a and the second air blowing hole b are opposite and communicated. When the clamping device clamps the workpiece to be clamped 500, the base 101 is connected to the air blowing pipe, and the first air blowing hole a is communicated with the air blowing pipe. That is to say, the air blowing pipe, the first air blowing hole a and the second air blowing hole b are sequentially communicated. When the air blowing pipe introduces gas, the gas sequentially passes through the air blowing pipe, the first air blowing hole a and the second air blowing hole b and enters the interior of the workpiece to be clamped 500, so as to purge the interior of the workpiece to be clamped 500.

[0027] Optionally, both the first air blowing hole a and the second air blowing hole b can be of structures such as square holes and round holes. The embodiments of the present application do not limit the specific structures of the first air blowing hole a and the second air blowing hole b.

[0028] In the embodiment of the present application, by directly inserting the boss 102 into the interior of the workpiece 500 to be clamped, the base 101 and the boss 102 can be brought into contact with the workpiece 500 to be clamped simultaneously, thereby clamping one side of the workpiece 500 to be clamped, which is beneficial to improving the stability of the workpiece 500 to be clamped and avoiding the risk of the workpiece 500 to be clamped falling during the manual installation and disassembly process. Moreover, by blowing air into the interior of the workpiece 500 through the first air blowing hole a and the second air blowing hole b, it is beneficial to blow out the residual cutting fluid inside the workpiece 500 and improve the product quality.

[0029] In an alternative embodiment, the first air blowing hole a and the second air blowing hole b are oppositely arranged, both the first air blowing hole a and the second air blowing hole b extend along the first direction A, the boss 102 protrudes from the surface of the base 101 along the second direction B, the second direction B is perpendicular to the surface of the base 101, and the first direction A can be parallel to the second direction B. That is to say, the extending directions of the first air blowing hole a and the second air blowing hole b are the same as the direction in which the boss 102 protrudes from the surface of the base 101.

[0030] In another embodiment, referring to Figure 3 as shown, the first direction A intersects with the second direction B. That is to say, the extending directions of the first air blowing hole a and the second air blowing hole b are different from the direction in which the boss 102 protrudes from the surface of the base 101.

[0031] In this embodiment, the first air blowing hole a and the second air blowing hole b are inclined, and the air blowing direction is different from the protruding direction of the boss 102. Therefore, the gas blown into the first air blowing hole a and the second air blowing hole b can directly blow to the inner wall of the workpiece 500 to be clamped and change the air flow direction, extend the air flow path, increase the residence time of the gas inside the workpiece 500 to be clamped, which is beneficial to improving the air blowing effect and avoiding the residual cutting fluid inside the workpiece 500 to be clamped.

[0032] In a further embodiment, the included angle between the first direction A and the second direction B is an acute angle, and the range of the acute angle is 10° - 30°. Optionally, the included angle between the first direction A and the second direction B is 15°.

[0033] In this embodiment, the included angle range between the first direction A and the second direction B is greater than 10°, to avoid the air flow being difficult to collide with the inner wall of the workpiece 500 to be clamped and change the direction due to too small an included angle, and avoid too short an air flow path; at the same time, the included angle range between the first direction A and the second direction B is less than 30°, to avoid the air flow colliding with the inner wall surface of the workpiece 500 to be clamped too frequently, which affects the stability of the workpiece 500 to be clamped.

[0034] Of course, in other embodiments, the included angle between the first direction A and the second direction B is an acute angle, and this acute angle can be greater than 30° or less than 10°.

[0035] In the solution of the present application, referring toFigure 2 and Figure 3 As shown in Figure 3 , the clamping device includes a sleeving member 100 and an embedded member 200. The embedded member 200 is the main component for forming the first air blowing hole a and the second air blowing hole b, and the sleeving member 100 is used to protect the embedded member 200. The sleeving member 100 is detachably sleeved outside the embedded member 200, and the embedded member 200 protrudes from the surface of the sleeving member 100. The part of the embedded member 200 protruding from the surface of the sleeving member 100 forms a boss 102, and the part of the embedded member 200 sleeved by the sleeving member 100 and the sleeving member 100 together form a base 101. That is to say, the base 101 is a split structure. Optionally, the sleeving member 100 can be directly sleeved outside the embedded member 200 or separated from the embedded member 200, so as to realize the installation and disassembly of the embedded member 200; alternatively, the sleeving member 100 and the embedded member 200 can also be detachably connected by means of snap connection, bolt connection, etc.

[0036] Moreover, both the first air blowing hole a and the second air blowing hole b are provided in the embedded member 200. Optionally, the embedded member 200 directly opens a through hole along the second direction B, and the through hole penetrates the embedded member 200, and the through hole directly forms the first air blowing hole a and the second air blowing hole b in the above text.

[0037] By adopting this embodiment, the detachable connection between the sleeving member 100 and the embedded member 200 forms the base 101 and the boss 102. When the wear of the embedded member 200 is relatively serious, the old embedded member 200 can be detached and a new embedded member 200 can be replaced. Therefore, the embedded member 200 can be installed and disassembled as needed, and the service life of the clamping device can be extended.

[0038] Of course, in other embodiments, the sleeving member 100 can be sleeved outside the embedded member 200 by means of welding, bonding, etc., that is, the sleeving member 100 and the embedded member 200 are connected in a non-detachable manner.

[0039] In an alternative embodiment, referring to Figure 2 As shown in Figure 2 , the embedded member 200 is provided with a stop projection 210. The stop projection 210 protrudes from the circumferential surface of the embedded member 200, and in the direction in which the embedded member 200 protrudes from the surface of the sleeving member 100, the stop projection 210 is in limit fit with the sleeving member 100. Specifically, the sleeving member 100 has an installation hole for the embedded member 200 to extend into. When the embedded member 200 extends into the installation hole, the stop projection 210 is in limit contact with the hole wall surface of the installation hole, blocking the movement of the embedded member 200 relative to the sleeving member 100, realizing the relative fixation of the embedded member 200 and the sleeving member 100, and further realizing the connection between the two.

[0040] Optionally, the stop projection 210 may be a block projection or a strip projection. The embodiments of the present application do not limit the specific structure and shape of the stop projection 210; the stop projection 210 and the insert 200 may be an integral structure or a split structure.

[0041] With this embodiment, the insert 200 is limited and cooperated with the sleeve 100 through the stop projection 210, so as to realize the detachable connection between the insert 200 and the sleeve 100. Compared with the detachable connection methods such as snap connection and bolt connection, this embodiment is beneficial to simplify the connection structure between the insert 200 and the sleeve 100, and is more convenient to replace and install the insert 200.

[0042] In an alternative embodiment, refer to Figure 2 As shown, the stop projection 210 is a strip structure, and the stop projection 210 extends along the direction in which the sleeve 100 surrounds the insert 200, that is, the stop projection 210 extends along the circumferential direction of the insert 200. That is to say, the stop projection 210 is a strip projection. Optionally, stop projections 210 are provided on both opposite sides of the insert 200, and both of these stop projections 210 are strip projections. Further optionally, the sleeve 100 is provided with an installation hole for the insert 200 to extend into, and the installation hole is a stepped hole, and the strip projection is in limit cooperation with the stepped surface of the stepped hole.

[0043] With this embodiment, the extension length of the stop projection 210 increases, then the area of the limit cooperation between the stop projection 210 and the sleeve 100 increases, which is more beneficial to the stable cooperation between the insert 200 and the sleeve 100, and realizes the stable detachable connection between the insert 200 and the sleeve 100.

[0044] In an alternative embodiment, refer to Figure 2 As shown, the sleeve 100 includes a base sleeve 110 and a protective sleeve 120. The base sleeve 110 is sleeved outside the insert 200. Optionally, the base sleeve 110 is provided with an installation hole for installing the insert 200, and moreover, in the direction in which the insert 200 protrudes from the surface of the sleeve 100, that is, in the second direction B in the foregoing text, the stop projection 210 is in limit contact with the base sleeve 110. The protective sleeve 120 is sleeved outside the base sleeve 110, the insert 200 protrudes from the surface of the protective sleeve 120, and the protective sleeve 120 is a flexible structure.

[0045] Optionally, the materials of the base sleeve 110 and the insert 200 may be the same or different. The base sleeve 110 and the insert 200 may adopt a rigid structure. Further optionally, the base sleeve 110 and the insert 200 may adopt a metal material; the protective sleeve 120 may adopt a rubber material or other flexible materials that can protect the base sleeve 110.

[0046] In this embodiment, the flexible protective sleeve 120 is used to protect the base sleeve 110 and the insert 200, reducing the risk of damage to the exposed insert 200 and base sleeve 110, improving the safety performance of the clamping device, and being more conducive to extending the service life of the clamping device.

[0047] Of course, in other embodiments, the sleeve member 100 may not be provided with the protective sleeve 120, that is, the sleeve member 100 may only include the base sleeve 110.

[0048] In the solution of the present application, referring to Figure 4 and Figure 5 As shown, the clamping device further includes a support base 300. The support base 300 serves as the installation foundation of the base 101, and the base 101 is disposed on the support base 300. Optionally, the support base 300 may also adopt a metal structure. Further optionally, the material of the support base 300 is aluminum. Moreover, the support base 300 is provided with a third air blowing hole c, and the third air blowing hole c is used to communicate with the air blowing pipe, and the third air blowing hole c is communicated with the first air blowing hole a. In this way, the air blowing pipe is directly connected to the side of the support base 300 facing away from the base 101, so that the air blowing pipe is directly communicated with the third air blowing hole c, and the gas sequentially enters the interior of the workpiece 500 to be clamped through the third air blowing hole c, the first air blowing hole a, and the second air blowing hole b.

[0049] Optionally, the third air blowing hole c may be a square hole, a round hole, etc. The present application embodiment does not limit the shape and structure of the third air blowing hole c.

[0050] In this embodiment, the support base 300 is used to support the base 101 and the boss 102. The support base 300 can directly fall on the ground, so that the base 101 and the boss 102 have a certain height and maintain a fixed position, and there is no need to manually control the base 101 and the boss 102 to clamp the workpiece 500 to be clamped, which is more conducive to freeing the hands and more convenient for clamping the workpiece 500 to be clamped.

[0051] Of course, in other embodiments, the clamping device may not be provided with the support base 300, that is, the clamping device may only be provided with the base 101 and the boss 102.

[0052] In an alternative embodiment, the clamping device includes a base 101 and a boss 102, and the base 101 is disposed on the support base 300. Optionally, the base 101 and the boss 102 are formed by the insert 200 and the sleeve member 100 described above.

[0053] In another embodiment, referring to Figure 5As shown, the number of the base 101 and the boss 102 is at least two, and the base 101 and the boss 102 correspond to each other one by one. At least two bases 101 are arranged at intervals on the support base 300. Optionally, the number of the inserts 200 and the sleeves 100 is multiple, and the support base 300 is provided with multiple inserts 200 and multiple sleeves 100 at intervals; moreover, the support base 300 is provided with multiple third air blowing holes c at intervals, and the third air blowing holes c are in one-to-one correspondence and communication with the first air blowing holes a. That is to say, each support base 300 is used to install multiple bases 101 and multiple bosses 102, and each base 101 contacts different workpieces to be clamped 500 respectively to clamp different workpieces to be clamped 500.

[0054] Optionally, the support base 300 extends along the third direction C, and the third direction C is parallel to the support plane of the support base 300. The support base 300 is provided with multiple bases 101 at intervals along its own extension direction. The third direction C intersects with the first direction A and the second direction B respectively. Optionally, the third direction C is perpendicular to the first direction A and the second direction B respectively.

[0055] Adopting this embodiment, the support base 300 installs multiple bases 101 and multiple bosses 102 at the same time, which can enable the clamping device to clamp multiple workpieces to be clamped 500 at the same time, facilitating the processing of multiple workpieces to be clamped 500 at the same time and improving the processing efficiency.

[0056] In an alternative embodiment, referring to Figure 5 As shown, the number of the support bases 300 is at least two. At least two support bases 300 include a first support base 301 and a second support base 302. The first support base 301 and the second support base 302 are arranged oppositely. The structures of the first support base 301 and the second support base 302 may be the same or different; both the first support base 301 and the second support base 302 are provided with bases 101. The base 101 provided on the first support base 301 is opposite to the base 101 provided on the second support base 302, and the base 101 provided on the first support base 301 and the base 101 provided on the second support base 302 contact both ends of the same workpiece to be clamped 500 respectively.

[0057] Optionally, both the first support base 301 and the third support base 300 extend along the third direction C, and both the first support base 301 and the third support base 300 are provided with multiple bases 101 along their own extension directions. The base 101 provided on the first support base 301 corresponds to the base 101 provided on the second support base 302 one by one. In this way, the number of workpieces to be clamped 500 clamped by the clamping device is equal to the number of bases 101 provided on the first support base 301 and is also equal to the number of bases 101 provided on the second support base 302.

[0058] With this embodiment, by providing at least two support seats 300, the clamping device can clamp both ends of the same workpiece 500 to be clamped by using different bases 101 and bosses 102, without cooperating with other clamping devices for clamping, which is more conducive to improving clamping stability.

[0059] Of course, in other embodiments, each clamping device may include only one support seat 300, that is, the bases 101 provided by the support seats 300 of different clamping devices can cooperate to clamp both ends of the same workpiece 500 to be clamped.

[0060] In an alternative embodiment, the support seat 300 and the base 101 can be fixedly connected in an inseparable manner such as by welding or bonding.

[0061] In another embodiment, the support seat 300 and the base 101 are detachably connected. Optionally, the support seat 300 and the base 101 can be detachably connected by means such as snap connection or bolt connection. Further optionally, as shown in Figure 4 the support seat 300 is provided with a first connection hole 310, and the base sleeve 110 is provided with a second connection hole 111, and the second connection hole 111 is a threaded hole. By passing a fastener 400 through the first connection hole 310 and extending it into the second connection hole 111, the support seat 300 and the base 101 are fixedly connected. Among them, the fastener 400 can be a threaded fastener 400 such as a bolt or a screw.

[0062] Optionally, the number of the first connection holes 310, the second connection holes 111, and the fasteners 400 is at least two, and the first connection holes 310 correspond to the second connection holes 111 one by one, that is, each base 101 is installed on the support seat 300 by at least two fasteners 400.

[0063] With this embodiment, the operator can install and disassemble the base 101 as needed, extending the service life of the clamping device.

[0064] Optionally, the first connection hole 310 can be a strip-shaped hole, and the extending direction of the strip-shaped hole intersects the third direction C, and the extending direction of the strip-shaped hole is parallel to the support plane of the support seat 300. In this way, by loosening the fastener 400, the position of the fastener 400 relative to the strip-shaped hole can be adjusted, so as to adjust the relative position between the base 101 and the support seat 300, which is conducive to accurately opposing the base 101 provided by the first support seat 301 and the base 101 provided by the second support seat 302, thus facilitating clamping of both ends of the same workpiece 500 to be clamped.
